ABSOLUTE MAXIMUM RATINGS
OPERATING CONDITIONS
Absolute maximum ratings are limits beyond which the
life of the integrated circuit may be impaired. All voltages
unless otherwise specified are measured with respect to
ground.

Note 1: Limits are guaranteed by 100% testing , sampling, or correlation with worst-case test conditions.
Note 2: Low Duty cycle pulse testing is performed at TA.
Note 3: This does not include the current from the AUI pull down resistors or the LED output pins.
